DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeder in a longline fishery, and more particularly, to a fishing line for a branch line attached to a mainline during the operation of a mainline drawn out from the hull of a fishing boat in a tuna longline fishery or the like. The purpose is to efficiently and accurately feed the bait that has been fed.

[0002]

2. Description of the Related Art In the tuna longline fishery, when a trunk line is thrown from the hull lancing machine into the sea, a fishing hook at the tip of a large number of branch lines attached to the trunk line at appropriate intervals is maintained. are Toesa to a predetermined <br/> constant position by Soesa food. This bait is usually performed about 3000 times in one rowing operation, and its quality is an important operation that greatly affects the catch.

[0003] Usually, the main ropes unwound by a line hauler are stored in a main rope storage box at the stern, and the littering operation is performed from the early morning of the next day . In this littering operation, the littering operation is basically a manual operation. As shown in FIG. 12, the crew of A puts the snap 3 of the branch line 2 tied to the main line on the line conveyor 1, as shown in FIG. It is arranged on the rope feeding machine 4 side, the fishing hook 5 is fixed on the anti-feeding machine side, bait 6 is fed on the fishing hook 5, and the crew of B operates the foot switch to move the conveyor 1 consisting of the pitch conveyor into one. Move in the stern direction D by pitch.

[0004] The crew member C waiting for binding holds the snap 3 of the branch line 2 reaching the end on the lasso conveyor 1 in the right hand, and is pulled out from a trunk line storage box (not shown) by a feeder 4. The main rope 7 is grasped with the left hand, and the snap 3 is tied to the main rope 7 based on the branch rope connection instruction sound of the throwing indicator, and the stern end rope 2
Hold the coil section 2a with the left hand so that it is straight without resistance.
One. Then, the crew of B waiting for feeding is about 2 km from the feeding position.
The 50 mm place is held by the right hand and the rope is ported at about 30 degrees in the port direction in consideration of the eddy current caused by the screw of the hull. Usually, about 3000 branch ropes 2 are fed manually once.

[0005]

However, in such a conventional feeding operation, since it is not possible to feed far away from the hull, the bait is often eaten by seabirds. The disadvantage is that the rate of food loss is high. In particular, when the bait is thrown within 6 m from the hull, there is a problem that the loss rate of bait increases due to the long time of staying on the sea surface due to the effect of the screw of the ship.
20% or more of the bait feeds are within 6 m. Furthermore, seabirds hooked on hooks often die, which is not preferable from the viewpoint of protection of the natural environment. In particular, tuna longline fishery is a pelagic fishery and cannot be carried out without the understanding of neighboring countries.

[0006] Further, since the conventional feeding operation is a manual operation, there is a limit in the improvement of the work efficiency, and it is difficult to continue feeding at an accurate place, and especially the feeding period becomes long. There is a problem that the physical and mental burdens of the crew are large when the crew is in trouble. In addition entangled Mikinawa 7 to each other at the time of Tonawa, or Edanawa 2 and Mikinawa 7 and the many that will at stake, deterioration of made rope ends up directly affect the catch, also at the time of stormy weather of the hull Because pitching and rolling become intense ,
Such feeding operations are particularly difficult.

Therefore, the present invention solves such a problem of the feeding operation in the conventional longline fishery, and makes it possible to mechanically efficiently and accurately move a branch line fed by a hook to a distant place. It is an object to provide a feeder for feeding.

[0008]

FIG. 8 shows the operation of this embodiment having such a configuration.
This will be described with reference to FIGS. First, the crew of A places the snap 3 of the branch line 2 tied to the trunk line on the lasso conveyor 1 on the trunk line feeding machine 4 side, and places the fishing hook 5 on the anti-feeding machine side in the same manner as before. The bait 6 is loaded with the bait 6 on the fishing hook 5, and the crew of B operates the foot switch to move the conveyor 1 composed of the pitch conveyor in the stern direction D by one pitch.

Next, the crew member C waiting for binding holds the snap 3 of the branch line 2 reaching the end on the lasso conveyor 1 in the right hand and draws it out of the trunk line storage box (not shown) by the feeder 4. The main rope 7 to be snapped is gripped by the left hand, and the snap 3 is connected to the main rope 7 based on the branch rope connection instruction sound of the setting indicator.

At this time, the crew of B is required to
The branch line 2 reaching the uppermost end is taken out from the conveyor, and the bait 6 loaded on the fishing hook 5 is placed on the gutter-shaped portion of the bait arm 21, and the branch line of the throw indicator is set. The power of C based on the binding indication sound
After the crew attaches the snap 3 to the trunk rope 7, the feeder 2
It is preferable that the motor 11 is driven by pushing a waterproof push button switch for turning on and off a controller attached to the motor 0. The crew of C ties the snap 3 to the trunk rope 7
After wearing, the crew of B immediately puts the bait 6 on the feeding arm 21
May be. Soesaude 21 by the rotation force of the motor 11
Feeding by rotation of the motor in a substantially horizontal plane and sudden stop of the motor 11
The abrupt stop of the arm 21 causes the feeding arm 21 to rotate approximately one-third of the center line of the ship at 120 degrees, that is, from the position at 60 degrees starboard to the reference position at 60 degrees port, as indicated by arrow F, in a substantially horizontal direction. Displacement allows the bait 6 loaded on the hook 5 to be fed to the reference position at 60 degrees on port. Thereafter, the bait 6 is sequentially fed so as to match the batting operation of the batting machine, and the push button switch is operated to continue the baiting.

As the motor 11, an AC servomotor that can smoothly and smoothly rotate even in a high speed range and that can freely adjust the rotation angle, rotation direction, and rotation speed of the output shaft 18 is used. Position of the bait 6 on the feeding arm 21 , that is, the feeding start position

It returns to the placement position , that is, the feeding start position . In addition, depending on the state of wind and waves, the rotation direction and rotation speed of the feeding arm 21,
Throwing angle relative to the ship center line, projecting down insertion distance has become arbitrarily changed.

FIGS. 9 and 10 are schematic diagrams showing the operation when the hull is at rest and when it is rolling. 9 shows a state in which the bulwark 24 is substantially planar, and FIG. 10 shows a state in which the bulwark 24 is inclined by an angle θ. A pair of swing stop shafts 30, 30 extending in the direction
Moves to the position 30 ', and the rocking stop shafts 30, 30 abut the base 23a of the bulwark mounting bearing during rolling of the hull, so that the elevation angle of the feeding arm 21 with respect to the sea surface is maintained substantially constant. Excessive tilting of 20 is prevented.

The above-mentioned rocking stop shafts 30, 30 are provided on a support plate 28 as a motor mount for the rocking flange shaft 29 (3 (3)
0φ × 100 l) Swing flange shaft 29 which is attached and suspends the AC servomotor 11 and the feeding arm 21 etc.
Is swingable by a bulwark mounting bearing mounted on the upper part of the bulwark, so that the rocking stop shafts 30 and 30 are attached to the bulwark mounting bearing (250 ×
The elevation angle of the feeding arm with respect to the sea surface can be maintained until it touches the upper surface of 125 × t = 12).

As understood from the above description of operation, the bait 6
The placement position of the bait arm 21 when placing the bait is the position of the bait arm 21 at the start of feeding, and the rotation direction of the bait arm 21 is a clock when the baiter 20 is mounted on the ship. The direction is counterclockwise when mounted outside the boat, but the bait 6 loaded on the hook 5 is thrown at a reference position of 60 degrees on port. Also, when the wind direction is from the port side in a rough sea, the feeding direction may be changed to the starboard side. Furthermore, the placement position of the bait 6 ,
That is, the feeding start position can be appropriately changed depending on the state of the sea or the wind direction in order to throw the branch rope 2 at the reference throwing angle.

[0025] If you turn off the push button switch for the controller of the on-off Soesaude 21 becomes free, the full
The feeding arm 21 is rotated in the state of
After setting the position of the bait arm 21 arbitrarily, press the push button switch.
Of the bait 6 on the feeding arm 21 by turning on the switch.
The placement position can be changed, and at the same time, the feeding position of the bait 6 can be changed. Also, the feeding position and distance of the bait 6
Has a rotation angle of the output shaft 18 of the motor 11 to the rotational speed thus an adjustable.

[0026] and Toesa by the acceleration of the 1/3 rotation from the mounting position of the bait 6, 1/3 by which to return to the loading position in the deceleration of rotation, projecting food and AC servo to put the angle of the reference Consideration is given to the prevention of danger to the crew by the feeding arm 21 when the motor is used in the high efficiency state, and to reduce the fatigue of the crew by shortening the feeding cycle to allow a margin time.

[0027] Therefore, to reduce the projected feed cycle by carrying out the above adjustment, to reduce the fatigue of'll Ri crew to be provided with a margin time, yet placement of the Soesaude 21 depending on the state of the wind and the sea The position can be manually displaced, and the throwing angle of the bait 6 with respect to the ship center line can be easily adjusted.

[0028]

As described above in detail, according to the feeder according to the present invention, the feeding arm keeps the predetermined rotation angle and the predetermined rotation speed by the rotation force of the motor, and performs a specific rotation in a substantially horizontal plane. By rotating in the direction and stopping abruptly, it becomes possible to feed the bait loaded on the fishing hook farther away from the hull, and it is possible to perform bait in a good rope condition. Further, Soesaude after Toesa is Ru <br/> be returned to the original mounting position by the reverse rotation of the motors. Preferred throw bait machine from the viewpoint of protection of the natural environment with food was Toesa along with this reduces the loss rate of the feed to eliminate the situation that eaten in seabirds is obtained. In addition, there is a great effect that the work efficiency is improved as compared with the conventional manual feeding based feeding operation, and the physical and mental burden on the crew is reduced even when the feeding cycle is lengthened.

Even when the hull rolls, the elevation of the feeding arm with respect to the sea surface is maintained at a substantially constant angle by the action of the pair of rocking stop shafts extending outward from both sides of the rocking flange shaft. Excessive tilting of the feeder can be prevented. In addition, the direction of rotation of the feeding arm, the throw angle with respect to the center line of the ship, and the throw distance can be arbitrarily changed depending on the state of wind and waves.

Therefore, according to the present invention, it is possible to mechanically and efficiently feed a trunk line to which a branch line tied to a fishing hook is tied, and to have a simple structure which is not damaged by waves. By obtaining a foraging machine, it is possible to improve the catch by improving the rope. That is, various items of feeding work such as rope formation, entanglement, damage to seabirds, feeding, feeding distance, feeding at long distances, work efficiency, feeding cycle, burden on workers, etc. Can be improved.
